I have an 86 Chevy Beauville with a 6.2, and VanDiesel is one of my all-time favorite vehicles, EXCEPT for the engine block coolant drain plugs, which are behind the engine mounts. I badly need to clean and flush the cooling system, and that flush requires draining the block. Does anyone have a suggestion/method for a flush?

Thanks, John. I might just end up doing the radiator only --- that would be much better that no attention at all. And I've looked at the freeze plugs as a possible alternate, but I always come back to, "They didn't really design it that way, did they??" As an engineer, this sort of lunacy hurts!

Perhaps there is a brass street 90 elbow with 3/8 MPT one side and flare fitting outlet, that I could install between the block and the engine mount. If I find one, I'll let you know!
